FISH-GUARD.

Specification of Letters Patent.

PatentedFeb. 17, 1914.

Application filed July 23, 1913. Serial No. 780,781.

To all whom it may concern:

Be it known that I, FRED GIESENHAUS, citizen of the United States,residing at Muscatine, in the county of Muscatine and State of Iowa,have invented certain new and useful Improvements in Fish-Guards, ofwhich the following is a specification.

This invention relates to an improved fish guard or screen.

The primary object of the invention is to provide improved means toprevent the entrance of fish into irrigating ditches, the said meanscomprising an adjustable or movable pipe section arranged to partiallyclose the inlet pipe of the irrigating ditch, the water supply for thelatter being 'received by way of the said inlet pipe from a tank orreceptacle within which the device comprising my invention is arranged.

It is a well known fact that a great number of fish enter the irrigatingditches during the filling thereof and as the water in the ditchesbecomes stagnant or is absorbed by the soil, the fish are left thereinsoon to die, and it is to overcome this objectionable and undesirablefeature that the present invention has been designed.

The invention still further resides in the provision of means in thenature of a suitable float member having an adjustable pipe sectionsecured thereto, which arrangement causes the said pipe section to riseand fall with the rise and fall of the water within the supply tank ofthe irrigating ditch.

The above and additional objects are accomplished by such means as areillustrated in their preferred embodiment in the accompanying drawings,described in the follow' ing specification and then more particularlypointed out in the claims which are appended hereto and form a part ofthis application.

In describing my invention in detail reference will be had to theaccompanying drawings wherein like characters denote like orcorresponding parts throughout the several views, and in which Figure lis a longitudinal sectional View illustrating the application of theinvention; Fig. 2 is an enlarged longitudinal sectional view of aportion of the adjustable pipe section and the means employed foradjusting or supporting the same; Fig- 3 is a section on the line 33 ofFig. 2; Fig. 4 is a top plan view of the adjustable pipe Section withthe float removed; and Fig; 5

is an elevation, partly broken away, of a modification. Beferring now tothe drawings, wherein is illustrated the preferred form of my inventionthe numeral 1 designates the original water supply which in the presentinstance is represented as a river or lake, along the bank of which asupply tank 2 is disposed, the latter having a lift gate 3 suitablymounted at one end thereof to regulate the supply of water necessary tothe operation of the invention. The irrigating ditch & receives itswater supply through the medium of an inlet pipe leading theremto thesaid pipe 5 being connected as at $3 to a vertically extending pipe 7leading into the tank 2 and projecting upwardly from the base or bottomthereof a suitable distance. Arranged over the pipe 7 is a slightlyenlarged pipe section 8 the lower end of which is open and the upper endof which is provided with an inwardly directed annular flange 9 topartially close the said pipe end and to limit the downward movement ofthe pipe section should the water within the tank become abnormally low.Rods 10 of which there are preferably three, extend upwardly from thepipe section 8 over which a suitable buoyant member or float 11 isarranged, the latter being loosely retained in proper place with respectto the rods 10 through the medium of cotter pins 12 extendingtransversely through apertures 13 formed within the said rods,thisarrangement permitting the adjustment of the float 11 with respect tothe pipe section'8 to regulate the water supply through an opening 14formed by the annular flange 9. The rods lOalso form a check or screento prevent the-entrance of fish into the pipe section 8. Ribs 15 projectlaterally from the outer face of the pipe section 7 the outer edges ofthe said ribs being engaged by the inner wall of the adjustable pipesection 8, this arrangement of the said ribs with respect to the pipesection 8 causing the latter to at all times remain out of engagementwith the pipe section 7 and to be telescopically held over and upon thesaid pipe section. 7

Referring now to the modification shown in Fig. 5, the float member 16illustrated therein is provided with a pipe section 17 composed of anysuitable light material, the said pipe section 17 being arranged over astationary pipe section 18 as illustrated, the

water supply in this instance however being admitted at the base of thepipe section 17' as indicated by the arrow in the said Fig. 5 and thenceinto the top of the pipe sec tion 18, this arrangement of the pipesection, one over the other, preventing the entrance of fish into thesupply pipe of the irrigating ditch.

Then it is desired that the water supply should be regulated, that is,either increased or diminished, the pins 12 are removed and adjusted inthe openings or apertures 13 proyided therefor to the desired height,thereby determining or regulating the distance between the under face ofthe float 11 and the opening 14, The pipe section 8 being of lightmaterial, it will be seen that the float 11 normally supports the saidpipe sec tion and causes the said section to move or automaticallyadjust itself according to the rise and fall of the water within thetank 2. The float member 11 being loosely arranged over the rods 10, thesaid float is normally supported by reason of the water within the tankin engagement with the pins 12, which ngageme t e fe t n pe Spacethrough which the water passes into the P ne a d henc t he 1 6 Pip 5 ofth irriga ng d c It will be seen from the above, taken in connectionwith the accompanying drawes tha d ubl che k o gua d s p. 7-0- ded. y thr e isien 0f he lift ga of the water tank; that the adjustable pipesection s t ll t m positioned c ntra y Over the Stationary pipe section7 by reason of the engagement between the said sect-ions and the ribs15; and that if desired, the ate upply to he rr g t ng dit h m y bentirely out off by lowering the lift gate 3 and adjusting the floatmember 11 until the opening 14 of the pipe section is entirely l sed.

In reduction to practice, I have found that the form of my invention,illustrated in the drawings and referred to in the above description, asthe preferred embodiment is the most efficient and practical; yetrealizing that the conditions concurrent with the adoption of my devicewill necessarily vary, I desire to emphasize the fact that various minorchanges in details of construction, proportion and arrangement of partsmay be resorted to, when required, without sacri- [icing any of theadvantages of my invention as defined in the appended claims.

I aving thus fully described my invention, what I claim as new anddesire to secure by Letters Patent, is

1. A fish guard for ditches including a supply tank, a d t h s pply pipesll g thereinto, and means operated by the rise and fall of the waterwithin the tank adapted to prevent fisdi from entering the said pipe, asand for the purpose set forth.

' 2. A fish guard for ditches including a supply tank, a ditch supplypipe extending thereinto, a pipe section adjustable vertically upon thesaid supply pipe, and a float secured loosely to the said pipe sectionfor supporting the latter, as and for the purpose set forth.

3, fish guard for ditches including a supply tank, a ditch supply pipeextending thereinto, an open end pipe section arranged over the saidsupply pipe, rods extending vertically from the top of the said pipesection and a float adjustably secured to the said rods adapted tosupport the said pipe section and automatically adjust the sameaccording to the rise and fall of the water within the tank, as and forthe purpose setiforth. i

4;, A fish guard for ditches including a supply tank, a ditch supplypipe extending he eiet n Op end Pipe section ar a ed to embrace thesupply pipe, an wardly directed annular fiange formed upon the top ofthe said pipe section for partially closing the mouth thereof, means formain taining the said pipe section against lateral movement independentof the supply pipe, a connected to the said pipe section adapted tosupport the latter and automatically adjust the same according to therise and fall ofthe water within the tank.

5. A fish guard for ditches including a supply tank, a supply pipeextending vertically thereinto, an open end pipe section arranged toembrace the said supply pipe, an inwardly directed annular flange formedupon the top of the said pipe section to partially close the mouththereof, a plurality of ribs radiating from the said supply pipe adaptedfor engagement with the said pipe section for maintaining the latteragainst lateral movement independent of the said supply pipe, aplurality of parallel vertically extending rods projecting from. the topof the said pipe section and a float member adjustably secured to thesaid rods adapted to support the pipe section and automatically adjustthe same according to the rise and fall of the water within the tank.

In testimony whereof I aflix my signature in presence of two witnesses.
